摘要
为了研究地震孕育过程 ,在弹性包体理论的基础上建立了流变介质的体源包体模型理论 .本文基于弹性包体模型的位移场的解析解 ,运用流变力学理论中的对应原理 ,导出流变体介质中 ,包体在任意一点的
Based on the three dimensional elastic inclusion model proposed by Dobrovolskii, we developed a three dimensional rheologic inclusion model and theory to study the earthquake preparation process. By using correspondence principle in the theory of rheologic mechanics, we derived the analytic expression of the viscoelastic displacement at an arbitrary point ( x, y, z ) in three directions of x axis, y axis and z axis ( i e. U(r, t), V(r, t) and W( r, t )) produced by a three dimension inclusion in the semi infinite rheologic medium defined by the standard linear rheologic model.
